Electric conductor patterns including antenna coils are formed on one surface of a film. Electronic components are fixed onto the film by a temporary fixing material. A cover film is laminated on the film so that the electrically conductive patterns and the electronic components are covered with the cover film. Simultaneously with the lamination, the electronic components are connected to the electric conductor patterns.

A work having a number of solder bumps on a substrate is mounted on a work positioning mechanism, and scanned by an optical micro head to measure errors of a mount posture of the work. Each stage is controlled to correct the errors, and thereafter, the apex positions of the bumps are scanned and measured. The measurement results are collected by a personal computer, and the measurement results together with control data of each axis are sent to a main personal computer and displayed on its screen. An error of an apex position of each bump from a regression plane is calculated, and if the error is smaller than a reference value, the work is judged to be good.

A method of measuring solder bumps formed on a substrate mounting a semiconductor element thereon includes mounting a work to be measured on a work position mechanism, and scanning the work by an optical micro head to measure errors of a mount posture of the work. Each stage is controlled to correct the errors, and thereafter, the apex positions of the bumps are scanned and measured. The measurement results are collected by a personal computer, and the measurement results together with control data of each axis are sent to a main personal computer and displayed on its screen. An error of an apex position of each bump from a regression plane is calculated, and if the error is smaller than a reference value, the work is judged to be satisfactory.

A method and an apparatus for measuring the height of an apex of an object with high accuracy without influence of the surface state of the object are disclosed. Correlation coefficients of respective positions of a waveform formed from digital data indicative of the height of the object detected by a head portion of a detector and a previously prepared standard waveform are calculated while moving the waveforms in the vertical and horizontal directions and the height of an apex position of the standard waveform at a position having a largest correlation coefficient from the calculated result is decided as the height of the apex of the object. Accordingly, the height of the apex can be decided from the whole detected waveforms without influence of local abnormality of the reflected light quantity waveform due to minute ruggedness or discoloration of the surface of the object.

A luminaire includes a light-emitting unit, a main body frame, a support frame, and a lighting unit. The light-emitting unit mounts light-emitting elements. The main body frame supports the light-emitting unit, and is formed rectangular having a hook-shaped engaging piece on one side. The support frame is formed rectangular surrounding the outer periphery of the main body frame, and has a groove-shaped receiving place to engage with the engaging piece of the main body frame, on one internal side. The lighting unit turns on the light-emitting elements.
